🎙️ MuteMe

MuteMe is a lightweight, high-performance Windows utility that allows you to mute/unmute your global system microphone via a customizable keyboard shortcut (Hotkey).

Designed specifically for gamers, it utilizes Raw Input to detect keystrokes with zero latency, working seamlessly even over Fullscreen Exclusive games or applications with elevated privileges, without losing focus.

✨ Key Features

• Reliable Global Hotkey: Uses Win32 Raw Input APIs (instead of standard hooks) to intercept keys. This ensures compatibility with competitive games (Valorant, COD, CS2, etc.) and anti-cheat systems.
• Audio Feedback: Plays confirmation sounds (Mute On/Off). It features a custom PCM byte manipulation engine to handle volume control without relying on heavy external libraries.
• Visual Feedback: Displays minimal, non-intrusive popups for volume adjustment and hotkey recording.
• System Tray Only: No cluttered windows. The app lives quietly in the System Tray.
• Ultra Lightweight: Compiled using Native AOT (Ahead-of-Time). The result is a single, self-contained .exe file that runs instantly and does not require the .NET Runtime to be installed.

🚀 Installation

1. Go to the Releases section of this repository.
2. Download the latest MuteMe.exe.
3. Place it anywhere you like (it is portable).
4. Run the application (Recommended: Run as Administrator).

🎮 Usage

The application runs in the background and is accessible via the System Tray (near the Windows clock).

Context Menu (Right Click)

Right-click the tray icon to access:

• Change Hotkey: Opens a popup to record a new key combination.
  • Supports single keys (e.g., F13, M, P).
  • Supports modifier combinations (e.g., CTRL + M, SHIFT + F10).
• Adjust Sound Volume: Opens a slider to control the volume of the feedback beeps.
• Exit: Closes the application.

⚙️ Requirements

• OS: Windows 10 or Windows 11 (x64).
• Privileges: To function correctly over games running as Administrator (often required by anti-cheats), MuteMe must also be run as Administrator.
